Myinvention relates to brick cleaners, and important objects of the invention are to provide a'device of'the character described which is conveniently operable for cleaning all sides of used bricks, which is simple in its construction and arrangement, durable and eflicient in its use, and comparatively in expensive to'manufacture and operate. o

, With the foregoing and other objects in view'which will appear as the description proceeds, the'invention resides in the combination and arrangement of parts'and in the details of construction hereinafter described'and' claimed, it being understood 1 that'changes in the precise embodiment of the: invention hereinafter disclosed can be made-within the-scope of what is claimed without departing from the spirit of the invention."

referencedesignate corresponding parts throughout theseveral views Figure 1 is a side elevational view of a brick cleaner, constructed in accordance with the invention, with parts thereof broken" away and partly in cross section;

'Figure'2 is a'top plan view of the devicewith parts thereof broken away and partly in cross section. I i

side view of a bearing pedestal. Referring in detail to the drawings 1 and 2, respectively denote apair of cylindrical brushes, which are disposed transversely horizontal and extend parallel to each other. The brushes 1 and 2 are spaced from each other'with the former positioned above the latter." 7 s '1 The brush 1" is fixed'on'a shaft '3 and the brush 2 is fixed'ona shaft 4;. The shafts 3 and 4 with respective brushes 1 and2 are supported by a pair of bearing pedestals 5, which are fixed to a base 6 and disposed vertically at respective ends ofthe brushes 1 a'nd2i i,

The shaft 4: is suitably journaled for ro tation,-as indicated at 7, in the pair of hearing pedestals 5. The shaft 4' is suitably qjournaled for rotation in the bearings 8.

The latter are slidablymounted for vertical adjustment in the bearing pedestals 5. Springs 9 are mounted in the bearing pedestals 5 and engage the bearings 8. The normal actions of the springs 9 force the bearings 8 upwardly in the bearing pedestals 5. Adjusting screws 10 are mounted in the top of the pedestals 5 and engage the bearings 8 for adjusting the latter in the pedestals 5, against or with the actions of the springs 9, to establish the desired spaced rer; lation of the brushes 1 and 2.

Another pair of cylindrical brushes 11 and 12 are disposed rearwardly of but in close proximity to the pair of horizontal brushes 1 and 2. The brushes 11 and 12 extend vertically in spaced relation and parallel to each other.

The pair of vertical brushes 11 and 12 are fixed on shafts 13, which are suitably journaled for rotation in the bearing supports 14 and 15. The latter are fixed in position on the base 6.

The upper end of each of the vertical shafts 13 carries a fixed bevel gear 16, which meshes with respective gears 17. The latter are fixed on a horizontally disposed drive shaft 18, which is suitably journaled for rotation in the bearing supports 14; and 15.

A pulley 19 is fixed to one end of the drive shaft 18, and similar pulleys 20 and 21 are so fixed to respective ends of the horizontal brush shafts 3 and 4:. The pulleys '19, 20 and 21 are all disposed on the same side of the apparatus and are aligned for engagement by a common belt 22. The latter also passes around an idler pulley 23 which is mounted for .tensional adjustment on the base 6.

A drive pulley 24 is fixed to the other end of the brush shaft 4 and is adapted for belt connection with the power supply apparatus operating the cleaner.

The belt 22 passes around the rearward and top periphery of the pulley 19, around the forward'periphery of the upper brush pulley 20, and around the rearwardperiphery of the lower brush pulley 21. The operation of the-belt 22 and of the bevel gears 16 and 17 is such that the pair of horizontal brushes 1 and 2 will rotate in brick between each of said pairs of brushes to be acted upon by the latter; a shield member partially enclosing one pair of said brushes, said shield member being formed to provide a pair of passages for the brick; one of said passages communicating with one of said brushes and theother of said passages communicating with the clearance between one pair of said brushes. 7

In testimony whereof I aflix my signature.

WILLIAM R. BANKSON.
